Harder Sudoku and Solver

Over the holidays I cam across an even more difficult sudoku in the LA Times. Here it is:

And as I mentioned in my last sudoku blog, I have a solver and it is now available here. It is a pretty simple app but does provide for solving a puzzle or just doing an iteration to get a few solved cells. And if you press the solve button from the start it will tell you how difficult the puzzle is. The one above is 32.2.
